Capitalism caused the genocide of untold native populations in Asia, Africa and the Americas, famines and environmental destruction around the world, destroyed the stability of most of Africa, the Middle East, Central and South America, and it has pumped so much carbon into the atmosphere that we have irreversibly altered the climate of the entire planet.

I'm not a Marxist or a proponent of LTV, but I do always get a giggle when people act like Communism caused the worst disasters in history. They're not great, to be sure, but at the Communists were mostly killing their own people instead of externalizing it to the entire planet.
